UNITED STATES LEO H. MOAN Am MILLER WADDELL, or WICHIITA, KANSAS BAILE'R Application filed November 3, 1930. Serial No. 493,109;

This invention relates to a bailer, the general object of the invention being to provide means for holding the bailer valve in open position after the same has been moved to the bottom of a well, so that the water in the bailer can escape therefrom.

Another object of the invention is to make the parts adjustable so that the device can be used on different sizes of bailers.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view, with parts in elevation, showing the invention attached to the stem of a bailer valve.

Figure 2 is a view of the valve and its associated parts, this view being taken a qua-rter turn from that shown in Figure 1.

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a section on line 4-4 of Figure 1.

In these views, the numeral 1 indicates the lower end of a bailer which is formed with the usual valve seat 2 for the valve 3, the shank of the valve being shown at 4, and the dart at 5.

In carrying out our invention, we provide a pair of elongated strips 6 which are arranged one on each side of the shank and the other on the opposite side thereof. These strips are each provided with a plurality of holes 7 for receiving a bolt 8 which passes through the stem and dart and through the rounded foot pieces 9 which are arranged at opposite sides of the lower end of the shank. These foot pieces are recessed as at 10 to receive the head and nut of the bolt. By providing a plurality of holes 7 for receiving the bolt, the strips 6 can be used on different sizes of bailers.

A latch 11 is pivoted at its lower end to the upper end of'each strip 6 and the head'of each latch is formed with a beveled part 12 for engaging the beveled part 2 of the seat so that as the bailer moves downwardly over the valve parts, these beveled parts 12, striking the beveled part 2, will cause the latches to move inwardly against the action of the springs 13 attached to the latches and engaging the shank of the valve and thus the heads of the latches will be caused to pass through the opening in the valve seat until the heads pass the seat, when the springs13 will cause the latches to move outwardly so that-the under portions of the heads will: engage'the seat and thus hold the valve'in open posltion. These under faces of the heads are roughened or provided with the teeth 14 to prevent the heads from slipping off the seat. Thus we have provided simple means for holding the valve off its seat so that the water from the bailer will pass to the bottom of the valve.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

hat we claim is 1. In combination with a bailer and its valve, strips connected to opposite sides of the shank of the valve, a latch pivoted at its lower end to the upper end of each strip, each latch having a head formed with a beveled upper part and a shoulder at its lower part whereby the latches will be forced inwardly by the valve seat when the bailer moves downwardly over the shank of the valve so that the heads of the latches will pass through the opening in the valve seat and the shoulders engage the top thereof to hold the valve in open position and a spring on each latch engaging the valve stem for holding the latches in their outward position.

2. In combination with a bailer and its valve, strips connected to opposite sides of the shank of the valve, a latch pivoted at its lower end to the upper end of each strip,
